How Fiber Optics works?

FTTH has obvious advantages for the consumer, both today and in the foreseeable future, offering improved performance for broadband services in comparison with those currently delivered primarily over copper networks.

SPEED

The speed comparison factor might be the most convincing one for you as customers. FTTH provides the highest possible speeds of Internet access downstream (from the network to the end user) as wellas upstream (from the user to the network). Mobile connections are much slower than FTTH, especially when several users are in the same area and share the available network. Satellite connections are also much slower than FTTH: they entail a delay, which hampers phone conversations and other interactive activities. Other fixed technologies, like ADSL, use metal wires - which are about 100 times slower than fibre to the home – to connect your home to the fibre city network.

Reliability

Even though FTTH speed is remarkable, we should consider other factors that also impact on the end- user service. Reliability is definitely one of these factors. An FTTH broadband connection offers an improved network reliability. Why?

Fibre optics transmissions are immune to this EMI (electromagnetic interference) since signals are transmitted as light instead of current, allowing them to carry signals through places where EMI would block transmission. While optical fibre is immune to electromagnetic interference, the transmission performance of other technologies like DSL is subject to random noise, as well as other interferences and crosstalk during operation which impact the overall throughput. Furthermore, optical components are extremely reliable in other ways as well (resistant to high temperature, humidity and fire and effective in specific environment such as undersea).

Security

The reliability factor is linked with security. To follow on the example above, magnetic fields and current induction work in two ways. They don't just generate noise in signal carrying conductors; they also make it possible to leak out the information that is on the conductor. There are no radiated magnetic fields around optical fibres; the electromagnetic fields are confined within the fibre. That makes it impossible to tap the signal being transmitted through a fibre without cutting into the fibre.

Secure fibre networks can therefore help protect content from piracy when other broadband solutions are more likely subject to these kinds of virtual threats or even viruses. As you can imagine, security and reliability are crucial to the data distribution in areas such as health services.
